New Jersey and Florida account for almost half of the 50 U.S. counties whose housing markets are most vulnerable to the economic effects of the coronavirus, an Attom Data Solutions report said.
Attom ranked 483 counties across the country based on the percentage of housing units receiving a foreclosure notice in the fourth quarter, the number of underwater properties in each county and the percentage of local wages required to pay for major homeownership expenses.

Thirty-six of the top 50 most vulnerable counties had median home prices in the $160,000-to-$300,000 range, the report noted.
Of the 10 most vulnerable counties, six are in New Jersey, including Sussex at No. 1 and Warren at No. 2.
"It looks like the Northeast is more at risk than other areas," Todd Teta, Attom's chief product officer, said in a press release. "As we head into the spring home buying season, the next few months will reveal how severe the impact will be."
Among the New Jersey counties that would be most affected, five are in the New York metropolitan area: Bergen, Essex, Passaic, Middlesex and Union. However, of the four counties in New York that Attom considered to be most vulnerable, only Rockland was in proximity to New York City.
